TOBIAS NEW', OF BROOKLYN, NEW YORK.

INSULATING CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 683,060, dated September 24, 1901.

Application filed February l1, 1901. Serial No. 46,812. (No model.)

T all whom t may concern.-

Be it known thatI, TOBIAs NEW, a citizen of the United States, and a resident ofthe borough of Brooklyn, in the city of New York and State of New York, have invented new and useful Improvements in Insulating Constructions, of which the following is a specification, reference being had tothe accompanying drawings, forming part thereof.

This invention relates to insulating constructions, and has for its objects increased effectiveness in preventing the interchange of heat or cold through the insulating construction, lightness of weight, and cheapness and simplicity of construction, ready transportation of parts prior to erection, strength and durability, non-inllammability, and substantial invulnerability to the effects of fire and Water, as well as the capacity of resisting all vapors, gases, and fluids to which such constructions are subjected, and other objects, which will hereinafter more fully appear.

My improved insulating construction comprises a block having an outer closed covering and having a plurality of partitions there-l in, these partitions being spaced or separated by air-spaces, so as to divide the interior of the block into a number of air-spaces between the partitions, and each of these partitions being of cellular construction with a plurality of air-spaces therein.

y invention further consists in making such outer envelop of wood and the inner partitions of paper and producing the cellular form of the inner partitions by building up such partitions of flat sheets of paper braced or stiffened and spaced by corrugated sheets of paper.

My invention further consists in making the outer envelop air-tight and fireproof and waterproof by coating the same and filling and closing up the pores thereof and filling the joints thereof with a fireproof and waterproof composition and also in making the inner'partitions fireproof and waterproof and with tight joints by coating the same and illing up the joints thereof with a fireproof and waterproof composition.

y My invention further consists in a Wall or -other structure or construction built up or made up of such insulating-blocks suitably cemented together; and my invention further consists in cementing such blocks together I with a iireproof and waterproof composition or cement and suitable fibrous material to ina crease the body and adhesiveness thereof.

My invention further consists in certain dedetails of construction, as will hereinafter more fully appear.

I will now describe the insulating construction illustrated in the accompanying drawings and will then point out the novel features in claims.

Figure l is a front elevation of a wall built up of insulating-blocks and embodying my invention. Fig. 2 is an end elevation of the same. Fig. 3 is a longitudinal transverse section of one of the insulating-blocks.

The insulating-block ct (shown'in section) is a wooden box made up of boards of wood secured together by nails or screws or otherwise and `forming a tight and substantial box. Within this box are secured cellular partitions b, these partitions being com# These cellular partitions h are separated from each other with intervening air-spaces, and, as shown, they are held apart by spacing-bars c, which may be of wood and which are shown as provided at the tops and bottoms of the partitions and also between the tops and bottoms thereof. lThe spacing-bars may be held in place by nails or otherwise, and, as will be seen, they space the partitions at these points in their Alength and further medially divide and separate the air-spaces between adjacent partitions.

The partit-ions b, the spacing-bars c,.and the outer covering d are coated with a reproof and Waterproof composition, and 'for such purpose I have employed soluble glass or silicate of soda treated with calcium chlorid. Other substances may, however, be used for suchl purpose. This coating is applied not only to the surfaces, but also to the joints, and acts as a cement and filling, making the cells or divisions and the structure as a whole IOO air-tight, and thereby insuring that the nuage. The iireproot' quality is especially valuable for the reason thatthe fire risk onrefrigerating and cold-storage plants is considered as very high, and therefore the introduction of a non-inflammable and reproof material in thc ,construction tends to greatly reduce this risk.

Ipreferto construct these insulatingblocks by building up the partitions b and spacingbars c upon one of the sides of the block as a base with the ends of the block secured in place thereon, and when the partitions and spacing-bars have been thus built up I secure the other side of the block in place. I then dip the structure in the fireproof solution, which may be silicate of soda, holding it, with the open ends, at the top and bottom, so that this solution flows into contact with all of the surfaces and joints thereof, and thereafter I dip the structure in the same manner in the reproof solution, which may be of calcium chlorid, and thereafterI finish the construction and inclosing of the box, first dipping in the fireproof and in the Waterproof solutions the parts not already coated. After the block has been constructed and closed I again dip it in the tireproof and in the waterproof solutions, so as to completely cover the surfaces and seal the joints thereof. It is of course evident that the parts of the blocks may be otherwise assembled and secured together and that modifications maybe made in the construction above described within the spirit and scope of my invention.

The insulating-blocks may be used as bricks or slabs in the construction of insulating walls, ioors, ceilings, or other, structures or constructions, a wall made up of such blocks being illustrated in Fig. 1. In building such a .wall or other construction I employ a cement of the fireproof and waterproof composition and place between the blocks a sheet or layer of fibrous material d, suoli as coarse cloth, to add to the body and adhesiveness of the cement and coat the surfaces with the fireproof and waterproof composition. Such a wall will therefore have air-tight joints and containing, as it does, a very large number of disconnected and dead-air spaces will afford a highly-eective insulation. The individual blocks maybe readily transported to t-he place of construction and will be light and readily handled, and the wall as a whole will be exceedingly light and inexpensive. Further, where transport-ation is over great distances the separate partitions and the separate boards for the boxes may be packed closely and the insulating-blocks built up at the place of erection, and thereafter the wall or other construction erected from the insulating-blocks.

What I claim as my invention, and desir to secure by Letters Patent, isi 1. An insulating construction comprising a block having an outer closed covering and having a plurality of spaced partitions therein with air-spaces between them, each of said partitions being of cellular construction with a plurality of air-spaces therein, substantially as set forth.

2. An insulating construction comprising a closed wooden box having a plurality of spaced partitions therein, with air-spaces between them, said partitions consisting of thin fiat sheets of paper spaced by corrugated sheets of paper, substantially as set forth.

3. An insulating construction built of separate blocks,each of said blocks consisting of a closed box having a plurality of spaced partitions therein with airspaces between them, each of said partitions being of cellular construction with a plurality of airespaccs therein, substantially as set forth.

4. An insulating construction built up of separate blocks, each of said blocks comprising a closed wooden box having a plurality of spaced partitions therein, with air-spaces between them, and said partitions consisting of thin fiat sheets of paper spaced by corrugated sheets of paper, substantially as set forth.
